What should I do when Win8/Win8.1 opens a folder?

If you don't have third-party protection software installed, the system will open Windows Defender by default. By default, scanning files will take up a lot of system resources and will cause the folder to open. Fake death; if other protection software is installed, Windows Defender should shut itself down, if it is not closed, close the "Windows Defender Service" service in the service.
If you only want to use Windows Defender as the base protection, you need to set a special case:
Open Windows Defender, click the “Set” tab, and there are corresponding exception settings on the left side. You can set some files, folders as an exception, or you can set a type or a process that is not checked. Of course, the exception setting is that you need to know that the programs you have are harmless. Without adding an exception, the scan results are only valid for this boot.
Idea 2: Restart the desktop window manager

Right-click on the target folder, select “Properties", and then click the “Advanced” button under the “General” tab In the dialog box, cancel “ in addition to the file attributes, it is also allowed to index the contents of this drive file & rdquo; in front of the check mark.

For the drive properties, in the "General" tab, uncheck the "Also on the file properties, and also allow indexing of the contents of this drive file" (not recommended for system disk) Operation will take a long time and is not necessarily successful).

In addition, according to the feedback from users, the size limit of the thumbnail cache file is canceled in the Windows 8.1 2014 Update (17025) version, so if you appear to be suspended due to the slow generation of thumbnails, If you don't want to completely turn off the thumbnail preview function, you may wish to wait a moment, and the next time you open the same folder, there should be no suspended animation.
